Has anyone had any success replacing a 1ghz logic board with a 1.2 ghz logic board in an ibook G4? Any stories of upgrading logic boards of any sizes in ibook G4s for that matter? I'd be interested to hear your stories. I've read some places that ibook logic boards of different processor sizes can't be trusted to fit. I'm just trying to verify this with someone who has attempted the repair themselves. I've been highly successful at upgrading processor speeds in PowerBooks, no I'm hoping it's the same in ibooks. B
